Teenage skateboarding sensations Arisa Trew and Ruby Trew are through to the semi-final of the women's park at the Olympic qualifier in Budapest.
The pair, who are not related, are on track to book Australian quota spots in the park discipline for the Paris Games, which get under way next month.
Arisa, 14, is looking to back up her gold medal from the Shanghai leg of the qualifier series held last month.
There she beat Japan's silver medallist from the Tokyo Games Hiraki Kokona and the reigning Olympic champion Yosozumi Sakura to win the women's park skateboarding event.
The young Queenslander came into the final in Budapest ranked second on the global standings.
After putting down two good runs overnight, she locked in a semi-final berth for Saturday alongside Ruby Trew, who is currently sixth in the global standings and also poised to clinch a women's park quota place.
"I'm just really excited to be out here for the final Olympic Qualifier before Paris," Arisa Trew said.
"It's just really cool … I'm loving skating and competing.
"The heat has been crazy … it's been really hot since we arrived."
Sydneysider Ruby Trew, 15, said she felt confident competing on the new Budapest course.
"I really like the course, it's one of my favourites so far," she said.
"Some of the lines are kind of tricky, trying to work out how much time we have, but overall I've liked it.
"I'm feeling pretty good, just working heaps on my tricks and trying to get them consistent while having fun on the way with my friends."
The men's park and women's street competitors are next in action, set to line up in the preliminary heats on Friday morning local time.
Tokyo gold medallist Keegan Palmer and top-ranked female Chloe Covell lead the Australian charge.
Palmer collected silver in the Shanghai event.
Only three skaters from one National Olympic Committee can compete at the Games, meaning that for countries with depth the battle will not just be to finish in the top 20 - athletes must rank in the leading three.
Skaters have been accruing rankings points during the world series over the past two years, but results in China and Hungary are worth nearly three times more.
